On the Water Sentinel installation page each product is a link to a video and on the product page there is a link to a PDF. I propose moving both of these links to each product page(s)

https://watersentinelfilters.com/installation/

Also, the video as are stored on the Water Sentinel website. It makes more sense to sotre them on You Tube. Being here it’s taking up server space but also it’s not as useful. On a social media platfor people can find them organically and it can serve to advertise.
